Implement Custom strcmp function

Code

#include <stdio.h>

int custom_strcmp(const char *a, const char *b) {
    // Your logic here
    const char* temp1=a;
    const char* temp2=b;
    while (*temp1!='\0'&&*temp2!='\0'){
        if (*temp1!=*temp2){
            return 1;
        }
       

        
        temp1++;
        temp2++;
    }
            if (*temp1=='\0'&&*temp2!='\0') return -100;

            else if (*temp1!='\0'&&*temp2=='\0') return 100;
    return 0;
}

int main() {
    char a[101], b[101];
    fgets(a, sizeof(a), stdin);
    fgets(b, sizeof(b), stdin);

    // Remove newline
    int i = 0;
    while (a[i]) {
        if (a[i] == '\n') { a[i] = '\0'; break; }
        i++;
    }
    i = 0;
    while (b[i]) {
        if (b[i] == '\n') { b[i] = '\0'; break; }
        i++;
    }

    printf("%d", custom_strcmp(a, b));
    return 0;
}
